Using keys for SSH authentication

    I use a SSH tunnel between two sites for rsync backups between servers. Currently I have to manually setup the tunnel, I'd like to use private/public keys to automate the process but can't see where I need to store the private key on the WRT.

    Any ideas?

    In the past I've used ssh-keygen but this isn't available on the tomato.

    I believe the private key is stored in the nvram variable sshd_hostkey

    this is how i did

    I did like this

    login to router with ssh/telnet

    type in:

    dropbearkey -t rsa -f key.secret

    the dropbearkey program will print out in the console a publickey. You must install that key on a shell/machine you would like to have access to

    login to the shell/machine

    edit the file in ~/.ssh/authorized_keys

    and paste the publickey in

    if you somehow manage to lose your publickey you can always type in dropbearkey -t rsa -f <your secret key> -y to get it printed out again

    There is a text box on the administration config page to allow the input of such keys...
